SPECIFICATION forming part of Letters Patent No. 374,670, dated December13, 1887.

Application filed Mnyl, i887.

Serial No 236,829. (No model.)

To @ZZ whom, it nutg/ concern,.-

Beit known that I, GEORGE J. GooDHUE, of Stevens Point, in the county ofPortage, and in the State of Wisconsin, have invented certain new anduseful Improvements i n Wood- Working Machines; and Ido hereby declarethat the following is a full, clear, and exact description thereof.

My invention relates to wood-working machines, being specially designedfor shaping the ends of the legs that form part of the timber structurefor mines, set forth in Letters Patent No. 35 8,261, dated February 22,1887 5 and it consists in certain peculiarities of construction andcombination of parts,to be here'- inafter described wit-h reference tothe accompanying drawings, and subsequently claimed.

In the drawings, Figure l represents a perspective view of a machineconstructed according to my invention; Figs. 2 and 3, elevations of acutter-head -employed in the machine, and Fig. 4 au elevation showingthe product of said machine.

Referring by letter to the drawings, A represents the mill-1loor; B, aplatform raised above the same, and C a chute, that preferably comprisesan inclined frame having a series of rollers journaled therein.

Preferably pivoted to the platform B are short skid-sections D, arrangedto be brought overthe chute Gand rest on long skid-sections E, pivotallysecured to said chute and eX- tended forward over a chuckframe,-F, thelatter being mounted on movable beams F F2. The forward ends of theskid-sections E are connected by rods G with hand-levers H, that are inturn suspended from the ceiling of the mill-room or other suitablesupport by rods I, and said levers are individually retained in anyposition to which they may be adj usted by means ofrack-bars J.

The movable beams F2, that aid in supporting the chuck-frame, havemounted thereon .racks K, to engage pinions L on a horizontal shaft, L,the latter having its bearings in boxes M on beams M, rigidly secured tothe mill-floor. One end of the shaft L carries a gear-wheel, N, thatmeshes with a pinion, O', on the adjacent end of a vertical shaft, O,the latter being journaled in a suitable framemounted in suitablebearings on the frame F.

By operating the levers H the timber is raised or lowered to get itcentered with the chucks Q R, and when this centering has beenaccomplished the spindle of the latter chuck is moved inward by means ofthe screw-rod R2 and hand-wheel R3, for the purpose of causing? both ofthese chucks to enter the respective ends of said timber. The chuck Q isfast on its spindle, while the one, R, runs loose. A gearwheel, S, issecured to the outer end of the chuck-spindle Q', to be engaged by apinion, S', on a shaft, S2, that is journaled in the frame F and carriesa belt-pulley, S. Power being applied to the chuck-spindle Q,through-the medium of the gear just described, the timber is slowlyrevolved,and when the handwheel O2 is operated :motion is transmitted tothe shaft L by means of the pinion O and gear-wheel N, thereby causingthe pinions L to exert their power on the racksK to actuate thecarriage, comprising the chuck-frame F and movable beams F F. As thecarriage is moved forward,the ends of the timber chucked therein comeinto contact with cutter-heads T, fast on shafts U, journaled in boxesV, that are secured to vertical posts W. Each shaft is provided with adrive-pulley,X,and can be moved in or out to adjust the cutter-heads Tto different lengths lof timber, said shafts being retained in theiradjusted position by setcollars X.

Each of the cutter-heads T comprises a cy lindrical shell closed at oneend and having its outer'periphery provided with a series oflongitudinal seats, o, to which are adj ustably secured detachableknives b, and said closed end of the shell has a series of radial seats,c, for adjustable saws d,the latter being preferably double-ended, andalso detachablefrom,

IOO

p is provided on its outer periphery with longitudinal seats ato whichare adjustabl y secured detachable knives f, and the closed end of thislatter shell has two or more radial seats, g, for detachably-connectedadjustable saws h. 4The shafts carrying the cutter-heads T are driven ata comparatively high rate of speed,and the timber on the carriage isfirst brought into contact with the saws d, said saws being slightly inadvance of the knives b. The saws d make a circular cut in thetin1ber,and being followed up by the knives b the ends of said timberare gradually chipped away to leave a round gudgeon, i, as shown by Fig.4, the movement of the carriage being limit-ed by a stop or stops, Y.Before the saws d and knives Z) on the larger shells of the cutter-headshave iinished their work the saws 7i and knivesf on the smaller shells,T, come into play against the timber to, in the same manner, cut awayenough of said timberto form circular shouldersj, adjacent to thegudgeons i?, one of such shoulders being also. shown in Fig. 4.

Vhile I prefer to make a shoulder, j, on both ends ofthe timber, thesmaller shells, T, carrying the saws h and knives f, may bc omitted fromeither one or both-of the cutterheads. v

When the cutting has been completed, th carriage is moved back clear ofthe cutterheads, and the timber being released from the chucks is rolledalong the skid-sections E to the inclined chute C and slides down to thcpoint of delivery.

Having thus fully desciibed my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a woodworking machine, a revoluble cutterhead that comprises twoshells of ,different diameters individually provided with radial saws'and longitudinal knives, all the knives on each shell heilig set at thesame angle and at the same distance from the axis Vof the cutter-head,substantially as set forth.

2. In a wood-working machine, a revoluble cutter-head that comprises twoshells of different diameters, radial saws detachably connected to aclosed end of each shell andadjustable thereon, and longitudinal knivesdetachably connected to and adjustable onthe outer peripheries of saidshells, all the knives on each shell being set at the same angle and atthe same distance from the axis of the cutter-head, substantially as andfor the purpose set forth.

3. In a wood-working machine, the combination of a recprocative frameprovided with revoluble chucks and revoluble heads,

each of which comprises two shells of differ` ent diameters individuallyprovided with radial `saws and longitudinal knives, substantially as setforth.

4. In a woodworking machine, the combination of 'a reciprocative framecarrying revoluble chucks, revoluble heads carrying radial saws andlongitudinal knives, skids extended over the chuck-frame beyond thecutter-heads, and suitable means for independently adjusting each skid,substantially as and for the purpose set forth.

5. In a wood-working machine, the combination of a reciprocative framecarrying revoluble chucks, rcvoluble heads carrying radial saws andlongitudinal knives, skids extended over the chuck-frame beyondthe-cutter-heads, a lever mechanism for independenti y adjusting eachskid, and suitable means for-retai ning said skids in their adjustedposition, substantially as and for thc purpose set forth.

6. In a wood-working machine, the conlbination of a reciprocative framecarrying revol'uble chucks, revoluble heads carrying radial saws andlongitudinal knives, a platform having skid-sections p ivotallyconnected thereto, a chute arranged adjacent to the platform,skid-sections extending from the chute over the chuck-frame beyond thecutter-heads, hand-levers having a rodconnection with each of the latterskid-sections, and rack bars arranged to engage the leverssubstantiallyas and for the purpose set forth.

7. In a woodworking machine, the combination of a reciprocat-ive frameprovided with revoluble chucks, laterally-adjustable shafts, a headmounted ou each shaft and provided with radialsaws and longitudinalknives, suitable means for imparting motion to said shafts, andindependentlyad j ustable skids cxtended over vsaid frame beyond thecutterheads, substantially as set forth. y

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee. in the' county of Milwaukee and State of Wiscousin, vin thepresence of two witnesses.
